According to the New York Times, the single-lensed eyepiece has returned as a trendy accessory for 21st-century gentlemen and hipsters alike.

It’s been spotted in editorial spreads, ad campaigns, and on the streets from Berlin to Brooklyn. What’s the reignited fascination with a fashion piece that was favored by 19th-century military men – and, well, a peanut – all about? I’m left scratching my head. Gentlemen, if you don’t want to look like you’re dressed for an extra role in a period-piece film, put the monocle down.
